Hair brush with slideable brush head

ABSTRACT

A hair brush with a slideable brush head that allows the brush head to be positioned on either end of the elongated handle to thereby providing ease of use by both right handed or left handed users. The elongated handle arrests the brush head in any desired position via the use of activating flanges that depress an activating rod held in place with compression springs with a cam and arresting balls in the center of the handle. When the activating rod is depressed, the cam is displaced by the compression springs which in turn releases the arresting balls creating a smooth surface of travel for the brush head therealong. The brush head may also be removed from the handle, if so desired, so that a brush head of a different circumference but the same inner diameter may be used. The handle is streamlined and elliptical in shape and contains rubber cushions for easier grip.

REFERENCE TO PRIOR APPLICATION

This application claims priority of the PCT patent applicationPCT/US18/39415, filed Jun. 26, 2018 entitled HAIR BRUSH WITH SLIDEABLEBRUSH HEAD by Master Poe Innovations, Inc.

BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates, generally, to the field of hairbrushes,and specifically toward a hairbrush having a slideable brush-head forflexibility of use.

Background of the Prior Art

Hairbrushes are extremely conventional for use in grooming hair as wellin styling the hair. Typically, a hairbrush is constructed of a handleand a brush head having bristles thereon of varying thicknesses andstiffness for use with a variety of hair types to achieve variousstyles.

U.S. Pat. No. 1,951,023 discloses' a brush including a handle having amass of sponge rubber secured thereto. The handle is disclosed to becollapsible and is composed of two or more telescoping members one ofwhich is embedded within the mass of the sponge rubber with an innermember being slideable into and out of an embedded member to form otherconvenient extending handles.

U.S. Pat. No. 2,641,012 illustrates a brush that has telescoping handleparts that form extendable sections of a hairbrush One part of thehandle section has a larger diameter while other sections areprogressively smaller whereby the various sections can telescope withineach other to form a longer or shorter handle.

U.S. Pat. No. 3,690,331 discloses a combined brush and comb including abody having tufts on an exterior surface of the body and a comb that maybe adjusted for various angles with respect to the body of the brush andincluded are retractable handles. In one embodiment the handles areextendible from either end of the brush body to facilitate its use byeither a right-handed or a left-handed person.

U.S. Pat. Nos. 8,353,076, 8,756,744, 8,752,231 and 8,782,842 to theinstant inventor Asta describe a variety of hairbrushes with slideablebrush heads. However, there were some shortcomings to these inventions,which the instant invention seeks to overcome, including a handle thatwas not comfortable for use due to short length, wide diameter andmechanical parts along the handle that were used as guides that were notcomfortable to the user.

It is the object of the instant invention to provide a hair brush withmultiples sized slideable brush heads that has an increased handlelength, a decreased handle diameter and an improved shape that providesease of use and comfort that was not possible with the devices of theprior art, including the prior patents to the instant inventor.

SUMMARY OF THE INVENTION

The inventive concept of the instant invention hereby disclosed is aspecific hairbrush that includes a handle upon which a grooming rollercan be moved from one end of the handle to the other or stopped in themiddle to all two hands for rolling, depending on the needs of thebeautician due to styling requirements or mere left- orright-handedness. The concept also allows for the grooming roller to bemoved from one end to the other, or removed altogether, during stylingand or storage, in order to provide a space for another hairbrush havinga different circumferential size or different brushing elements as longas the inner diameter remains the same so as to conform to the outerdiameter of the handle.

The preferred embodiment of the instant invention encompasses a hairgrooming device comprising: a brush head that is substantially round,having a first end and a second end and having a hollow ellipticalcenter; an elongated handle having an exterior top half, an exteriorbottom half, an interior created by the attachment of said exterior tophalf with said exterior bottom half, a first end and a second endwherein said brush head is movable between said first end of saidelongated handle and said second end of said elongated handle along saidexterior top half and bottom half wherein said brush head has the sameinner elliptical diameter as said elongated handle; a first aperture insaid top half substantially halfway along the length of said handle; asecond aperture in said bottom half substantially halfway along thelength of said handle wherein when said top half and said bottom halfare connected a first opening and a second opening are created, bothsaid first and second openings being positioned substantially onopposing sides of said handle substantially halfway along the length ofsaid handle; a first activating rod extending from said first end ofsaid elongated handle and having a first activating flange proximatesaid first end and a first activating clevis proximate said handlecenter; a second activating rod extending from said second end of saidelongated handle and having a second activating flange proximate saidsecond end and a second activating clevis proximate said handle center;a scissor-style spring having doubly opposing inclined planes and beingpositioned between said first activating rod and said second activatingrod; a first arresting tip connected to the scissor spring andpositioned in said first opening; a second arresting tip connected tothe scissor spring and positioned in said second opening; a firstcompression spring between said first activating flange and said handle;a second compression spring between said second activating flange andsaid handle wherein when one of either of said first or secondactivating rods is depressed through the application of force to eithersaid first or second activating flanges, said first or second activatingclevis displaces said inclined planes of said scissor spring therebymoving said first and second arresting tips in a radial direction insideof said interior of said handle thereby allowing said brush head toslide therealong until said first or second activating flange isreleased wherein said first or second activating clevis releases, saidscissor spring returns to its original position and said first andsecond arresting tips return to said first and second openings and saidbrush head is secured to said handle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Turning to the drawings, the preferred embodiment is illustrated anddescribed by reference characters that denote similar elementsthroughout the several views of the instant invention.

FIGS. 1-7 illustrate the preferred embodiment that discloses a hairbrush with a slideable brush head assembly. 40 that has an ellipticalhollow barrel 42 with a plurality of bristles 44 extending radiallyoutward therefrom. The internal chamber 48 of the brush head assembly 40receives and snugly houses an elongated slideable handle assembly 8having a top half 10 and a bottom half 12 that together form anelliptical gripping portion with an internal chamber 50 therein.

Inside of the top half 10 and the bottom half 12 is a substantiallyconcave shape with a series of width-wide ribs 54 that repeat along thelength of the handle assembly 8. Each rib 54 terminates on one end witha male portion 52 and on the other end with a female portion 56. Thesemale 52 and female portions 56 are assembly posts and there are six ofeach per handle 8 per side. They are designed in such a way that thehandle 8 is doubly symmetrical, i.e., each handle half can be used as atop 10 or a bottom 12 and it can be turned 180 degrees and maintain itsstructure. They serve as a means to secure the handle halves 10, 12together. They also serve as guides for the activating rods 22, 24 torestrict the rods to only axial inward and outward movement.

In the center of the handle assembly 8 is a post 14 for the placementtherein of a scissor spring 82 and accompanying arresting tips 26, 28.The cam 30 has a substantially rectangular shape with a hump 36 oneither side.

In the internal chamber 50, placed in the lengthwise direction, ishoused a plunger 70 which is split in half creating a right sideactivating rod 22 and a left side activating rod 24 wherein the scissorspring 82 is placed therebetween. Each activating rod 22, 24 terminatesin an activating flange 22 a, 24 a that extends beyond the length of thehandle assembly 8 top 10 and bottom 12 and a pair of compression springs32, 34 are positioned between the activating flange 22 a, 24 a and thehandle rib 8 a and whose purpose is to keep the activating rods 22, 24pressing outward when not in operation. They also provide a resistingforce when the activating flanges 22 a, 24 a are depressed.

Both the top portion 10 and the bottom portion 12 of the handle assembly8 have two lengthwise recesses, totaling four 72, 74, 76, 78 into whichrubber grips 62, 64, 66, 68 are placed for comfort when in use. To movethe brush head assembly 40 along the length of the handle assembly 8,the plunger 70 is activated through depression of one of the activatingflanges 22 a, 24 a at which point the corresponding the compressionsprings 32, 34 is likewise depressed and the corresponding activatingclevis 22 b, 24 b is moved axially. This causes the inner inclinedplanes of the activating clevis to slide along the inclined planes ofthe scissor spring which in turn causes the arresting tips to moveradially inward making it so that the arresting tips 26, 28 are nolonger abutting into the handle assembly 8 and therefore no longerimpeding the path of the brush head assembly 40 therealong.

Once the arresting tips 26, 28 retract inward, the brush head assembly40 can slide off the handle 8. As the pressure is released from thechosen activating flange 22 a, 24 a the reverse happens, i.e., thecompression springs 32, 34 push the arresting rods axially outward,thereby causing the scissor spring 82 to return to its normal positionsand allowing the arresting tips 26, 28 to extend into the recess hole16, 18 thereby securing the barrel 42 of the brush head assembly 40thereon. The brush head assembly 40 may also be removed from the handle8, if so desired, so that a brush head 40 of a different circumferencebut the same inner elliptical diameter may be used.

The description above describes how to remove the brush head from thehandle. However, it is important to note that the mechanism of theinstant invention allows for installation of the brush head onto thenaked handle without having to depress the activating flanges.

The invention illustratively disclosed herein suitably may be practicedin the absence of any element which is not specifically disclosedherein.
